Herrera Hernandez Nora Gabriela 1. Borquez Jorge 2. The research proposes to obtain a basea acid-base indicator from the acide of the arils of the Punica granatum L. The indicative actions of the fruit extract Punica granatumL. Finally, it was tye that the pH variation is one of the factors that significantly affected the color of the extract of the Punica granatum L.

The analytical chemistry uses synthetic indicators in order to verify the changes of pH according to the color variation, currently these valuation processes do not use natural indicators, generating inconveniences in the response produced by the discharge and response processes, a negative impact on the environment environment 157. Anthocyanins to red increases in methoxylation 4the what is the ph scale range for acids and bases of anthocyanins becomes more resistant to variations in pH when found as products condensation with catechins in the presence of aldehydes 3presenting 4 different stable structures: flavonous ion, chalcone, quinoidal and pseudobase.
